The dryer is a dry air generator for drying plastic material.
The dryer may have the following uses:
• In single-hopper systems.
• In multi-hopper systems.
In a single-hopper system the material is dried in a single hopper and then sent to
the processing machine.
In a multi-hopper system two or more hoppers are used: the material is dried
in the main hopper and stored in the secondary (or holding) hoppers at the
appropriate temperature until it is to be used.
In drying systems for PET type plastic material, there is only one secondary (or
holding) hopper, known as a split hopper.

Safety rules for handling, lifting, packing, and unpacking
1. The machine must be handled by expert personnel in accordance with
statutory health and safety regulations.
2. Use handling equipment that conforms to the safety requirements stated in
"Machinery Directive" in force. The handling equipment must be accompanied
by documentation certifying its conformity to the above requirements and
must be capable of bearing the weight of the machine plus its packing and
any accessories installed before the final positioning of the machine. Carefully
follow any instructions marked on the machine packing (the weight is given on
the outside of the pack). Do not use ropes or chains to harness the pack.
3. All handling operations must be performed with the machine completely
empty, i.e. with no process materials or fluids inside it, and with any external
support structures removed.
4. All the machine parts involved in the lifting operation are sized for handling
solely the machine with no accessories installed (unless otherwise indicated).
5. If the machine is lifted with steel cables, make sure that its weight is evenly
distributed over all the lifting points and that the strain on the cables is uniform.
The angle between each cable and the horizontal plane must not be less than
45°.
6. Fasten any loose parts. Make sure that the load is properly balanced and
securely fastened to the handling equipment. Always proceed with the utmost
caution to avoid injuring persons or damaging the machine.
7. All persons not involved in operating the means of transport must be kept at a
safe distance from the moving load.
8. Position the machine on a perfectly flat and level surface of suitable size and

Non original instructions obtained by translating the original manual written in Italian
construction in relation to the weight and dimensions of the machine.
9. After removing the packing, check that all parts of the machine are present
and in good condition. If you have any doubts, do not use the machine:
contact the PIOVAN Technical Service Department or an authorised service
centre. The packing materials must be disposed of in accordance with
statutory waste disposal regulations.

ENGLISH 16
4. Operation
1. In the machine there are two towers that contain molecular sieves, with high
moisture absorption capacity.
2. The two towers go through an alternating process cycle (i.e. drying cycle)
and regeneration cycle (while one tower is doing the process cycle, the other
is doing the regeneration cycle).
3. In the process cycle, the blowers send the moist air coming from the hopper
to the bed in the process phase. Here, the air is dehumidified by the molecular
sieves and then sent back to the hopper, in order to remove more moisture
from the plastic material before re-entering the cycle.
4. The purpose of the regeneration cycle is to remove the moisture from the
tower that has just completed a process cycle (to prepare it for the next cycle).
This cycle is in two phases:
a. Heating phase: in this phase, heated air is sent through the tower to
remove the moisture absorbed by the molecular sieves in the previous
process cycle.
b. Cooling phase: in this phase, cold air is sent through the tower to bring the
molecular sieves to the optimal temperature for another process cycle.
5. At the end of the regeneration cycle (i.e. when the tower in the regeneration
phase is ready to start another process cycle), the tower switchover occurs:
the tower that was in the process cycle goes to the regeneration cycle and
vice versa.

8. Energy Saving Application

8.1. Adjust the coolant (optional)

To guarantee constant working temperatures and keep energy consumption to
a minimum, the flow rate of the cooling liquid is regulated by automatic by-pass
valve YV9 (see Fig. 15 - Page 39).
In this way it is possible to reduce energy consumption due to an excessive
cooling of the air returning to the dryer, thus avoiding a greater demand of
heating power to maintain the predetermined Set Point.

Non original instructions obtained by translating the original manual written in Italian
Fig. 15

39 ENGLISH
8.2. Adjust the process air (optional)
The reduction of energy consumption may also be achieved by suitably
regulating the process air flow rate. The air flow rate is regulated according to
the hourly production rate of the processing machine by managing the automatic
valve YV8, controlled by dryer’s electronic management system (see Fig. 16 -
Page 40).
At the same time, the system also controls the level of material in the hopper in
order to ensure the correct degree of drying.
The regulating parameters are set during testing of the system and may be partly
adapted to the specific process requirements.
